Thalassaemia is an inherited blood disorder and is a significant public health alarm in Malaysia
with many not knowing they are carriers of this haemoglobin disorders. Materials and methods: This study
conducted a one off collection of blood samples from 72 Malays students of International Islamic University
Malaysia (IIUM) in Kuantan. Blood samples were subjected to conventional haemoglobin analyses that include
full blood count and picture, HPLC, Haemoglobin electrophoresis and H-inclusion test. All samples were also
genotyped for alpha thalassaemia–1 of Southeast Asia (a-Thal1SEA). Result: There were 17(23.6%) students
who were diagnosed as thalassaemia carriers. Out of this, four (5.5 %) and six (8.3 %) students were presumptive
β-thalassaemia trait and Haemoglobin-E trait as determined by the HPLC assay respectively. Nine
(12.5%) students were genotyped a-Thal1SEA among whom two were also β-thalassaemia carriers. All thalassaemia
cases had MCH of < 27pg. Nonetheless, two out of six Haemoglobin-E trait and three out of nine
a-Thal1SEA carrier had MCV value of >80fL. Two out of four (50%) presumptive β -thalassaemia trait and one
out of six (17%) students of presumptive Haemoglobin-E trait had family history of thalassaemia respectively.
Conclusion: The high occurrence of the three common types of thalassaemia carrier (β, Hb-E and a-Thal1SEA
thalassaemia) in our small group of subjects could be due to better participation of students who had family
history of thalassaemia. The study reaffirmed the importance of molecular study for detection of alpha-thalassaemia
and the use of MCH value of <27pg rather than MCV value of < 80fL for prediction of thalassaemia.

Atherosclerosis in cardiovascular disease (CVD) is a growing health problem, especially in developing
countries. Hyperlipidemia is known as a dominant risk factor for the development of atherosclerosis. This
study was designed to investigate the effects of Eurycoma Longifolia (EL) also known as Malaysian Ginseng/
Tongkat Ali on the testosterone level, biochemical changes of lipid profile and intima media thickness (IMT)
in rats fed on high-fat diet. Twenty young, adult male Sprague-Dawley (SD) rats were housed for 12 weeks.
After one week of acclimatization, they were randomly divided into four groups of 5 animals each and
treated for 12 weeks as follow: Group ND was given only normal diet, group NDEL was given normal diet and
EL extracts (15mg/kg) dissolved in distilled water, group HFD was given only high fat diet and group HFDEL
was given high fat diet and EL extracts (15mg/kg). Rats which were treated with EL (NDEL and HFDEL)
showed a significant increase (p<0.05) in the testosterone levels. There was a significant decrease (p<0.05)
in triglyceride (TG) in HFDEL group compered to HFD group. The histological sections of aortas revealed a
significant decrease (p<0.05) in IMT in HFDEL as compared with HFD group. No histological changes were
observed in NDEL group compared with ND group and there was no significant difference in IMT values
between NDEL and ND. These findings suggest that EL is a promising protective agent against atherosclerosis
induced by high-fat diet.

Polymorphisms within the β2-adrenergic receptor (ADRB2)
gene have been repeatedly linked to hypertension. Among
the ADRB2 polymorphisms detected, Arg16Gly and Gln27Glu
codons are considered the two most important variations.
The amino acid substitution at these codons may lead to
abnormal regulation of ADRB2 activity. The aim of the
present study was to assess the association between ADRB2
polymorphisms and hypertension. This case-control study
consisted of 100 unrelated subjects (50 hypertensive and 50
matched normal controls). Arg16Gly and the Gln27Glu
polymorphisms were analyzed by polymerase chain reactionrestriction
fragment length polymorphism assay. There were
no significant evidence of association in allelic and
genotypes distribution of Arg16Gly and Glu27Gln with
blood pressure and hypertension. These findings suggest
that the variation within codon 16 and 27 of ADRB2 gene
were unlikely to confer genetic susceptibility for
hypertension in our population samples.

Background: Synovial sarcoma (SS) is a rare cancer and accounts for 5-10% of adult soft tissue
sarcomas. Making an accurate diagnosis is difficult due to the overlapping histological features of SS
with other types of sarcomas and the non-specific immunohistochemistry profile findings. Molecular
testing is thus considered necessary to confirm the diagnosis since more than 90% of SS cases carry
the transcript of t(X;18)(p11.2;q11.2). The purpose of this study is to diagnose SS at molecular level
by testing for t(X;18) fusion-transcript expression through One-step reverse transcriptase real-time
Polymerase Chain Reaction (PCR). Method: Formalin-fixed paraffin-embedded tissue blocks of 23
cases of soft tissue sarcomas, which included 5 and 8 cases reported as SS as the primary diagnosis
and differential diagnosis respectively, were retrieved from the Department of Pathology, Tengku
Ampuan Afzan Hospital, Kuantan, Pahang. RNA was purified from the tissue block sections and
then subjected to One-step reverse transcriptase real-time PCR using sequence specific hydrolysis
probes for simultaneous detection of either SYT-SSX1 or SYT-SSX2 fusion transcript. Results:
Of the 23 cases, 4 cases were found to be positive for SYT-SSX fusion transcript in which 2 were
diagnosed as SS whereas in the 2 other cases, SS was the differential diagnosis. Three cases were
excluded due to failure of both amplification assays SYT-SSX and control β-2-microglobulin. The
remaining 16 cases were negative for the fusion transcript. Conclusion: This study has shown that
the application of One-Step reverse transcriptase real time PCR for the detection SYT-SSX transcript
is feasible as an aid in confirming the diagnosis of synovial sarcoma.
